WINDOW Application filed July 3; 1931. Serial No. 548,560.

Th-isinvention relates to improvements inthe construction of windowsasused in dwelling houses, office buildings and similar structures andisanimprovement on my Patent #1,? 78,97 8-, dated, October 21st,. 1930, forwindow.

In my Patent, #1,? 7 8,978, I have provided a window sash having anouter and an inner frame and cooperative means in the outer and innerframes whereby the inner frame is adapted to be pivoted and slid withrelation to'the outer frameand which is so hungas to; permit turning ona vertical axis whereby either side is renderedv accessible.

My said Patent, #L,778,978,. further provides for the construction of awindow having an outer and an inner frame wherein the inner frame can heslid along channels in the upper and lower members in the outer framefrom one end of the opening to theotherend thereof and freely swinglaterally at any point along thev channels, and wherein the inner framemay be completely reversed or turned inside out and completely confinedin reversed position within the outer frame.

ItisLan object of the present invention to. provide means to facilitatesliding ofv the auxiliary or inner frame with respect to the outer framealong channels in the upper and lower members of. the outer frame, andto.

facilitate the inner frame being swung laterally atv any point along thechannels, and for this purpose I employ a. rack and pinion arrangementcooperatively associated with revolvable means.

A further object of the invention is to provide a sash having an outerframe and 5a slidable reversible inner frame and cooperative means inthe frames whereby theinner frame. is prevented from canting by beingheld parallel with relation to the sides of the outer frame and invertical alinement, during the. sliding operation.

7 A furtherobject of the invention is to provide a window sash having anouter frame and-a swingable and reversible inner frame. and which issimple in construction, efficient in purpose and use and economicalincost.

Afurtherobjectof the inventionis to provide a window sash having anauxiliary sash pivotally arranged within and adapted to swing withrelation to an outer sash, andv which the pivotal means is supported inbearings which also provide means to reins force the inner corners of;theauxiliary frame.

These and other such Ob]6CtS,- as neatness in appearance, ease 1nmanipulation and ready substitution for the common. type of sash, A

are accomplished by the novel construction,

combination and arrangement ofparts here: inafte-r described and shownin the accompanying drawing, constituting a material: part of thisdisclosure, and inwhich:

Fig. 5 is a cross-sectional View taken along line 5- 5 of Figure 1andshowing the Win dow lock in locked position.

Fig. 6 is a view showing a portion in crosssection of one of the'sashes,the locking member being shown'i'n unlocked position.

Fig. 7- is a sectional view taken online 7-7 of Figure 1. Fig. 8- is aView of part of the-sliding-and pivoting mechanism. The casing shown isin all respeotsof the usual type of construction, comprising a pair. ofspaced jambs 10' connected by a lintle 11 at their top anda sill 12 atthe bottom.

Both jambs are channelled at their approximate inner surfaces andprovided with 9 parting strips 1313"13 toproduce grooves 147-15, inwhich are slidably re ceived sash frames 16'1Z, respectively, top andbottom. i

Each sash comprises an outer and an inner or auxiliary frame which are,in the embodiment shown, regular rectangles adapted to take the place ofcommon sashes for which they may be substituted. The outer frames haveat their inner edges inreaching flanges, as at 16. As the constructionof both sashes 1617, are identical, only one will'be described. Y

The inner surfaces of the upper andlower elements 8 and 9, respectively,of each outer frame 24, are grooved or"rabbeted longitudinally toreceive channel guides 18, preferably metallic, having vertical walls 18and 18, the said guides 18 being held by fastenings in fixed positionson the frame. Provided on the upper end of wall 18", of each channel 18,is a rack 19, preferably metallic. The rack 19 may form an integral partofthe channel 18 or may comprise a separate element secured thereto inany suitable manner. The inner frame 21,in which is fixed a transparentplate 22, as glass, is arranged, in a manner hereinafter provided, toslide along channels 18, and pivot or swing with relationto the outerframe24. -A side 25 of the inner frame is grooved its entire length asshown at 26 to loosely receive a rod 27 having its ends projectingbeyond the said side of the inner frame, the ends'of the rod projectingwithin the channels 18, the bottom end of the rod being rounded as shownat 28 and touching the base of the bottom channel.

The side 25 of the inner frame is secured to the top and bottom elementsof the frame by the corner bracket straps 29; which are perforated asshown at 30 (Fig. 3), to provide bearings for the rod 27. Secured toand'proximate each end of the rod is the inner race 31 of a ball bearingto which is revolvably mounted, through the instrumentality of the balls32, the outer race 33, the said ball bearing being adapted to fitbetween the walls 18 and 18", and to revolvably engage with either wallwhen the inner frame is slid along the channels, the said wallsproviding tracks for the ball'bearing. In

lieu of ball bearings, rollers 34, as shown in Figure 4, may beprovided.

Interposed between one ball hearing or roller and the top end andbetween the other ball bearing or roller and the bottom end of the side25 of the inner frame and mounted on the rod 27 are pinions 36 forengagement with the racks 19. The pinions are fixed to the rod by pins35 so that the rod rotates with the pinions. A cotter collar pin'37 toengage a hole in the top of the rodmay be provided to facilitate removalof the inner frame in the event of repairs becoming necessary. v

In the construction just stated, the rollers or ball bearings are freeto revolve with relationto the rod and therefor with relation to thepinions fixed on the rod. The rod being mounted for rotation in thebearing brackets 29 revolves with relation to the inner frame andpermits the inner frame being swung about the rod as a pivot.

I have thus provided means for sliding with ease the inner frame alongtracks in the top'and bottom members of the'outer frame without canting,the inner frame by this construction being constantly held in verticalalinement, and parallel with the sides of the opening of the outer frameduring the sliding operation, and capable of being frame 16 inboth ofits upright elements, are metal casings 40, carrying cupboard latches 41provided with knobs accessible from the front of the casings and urgedinto engagement with the sockets 42, on the inner frames by coiledcompression springs as shown.- I i Fixed in each side of thefrontmember-of each inner frame are hand grips 43by which theglasspanels or inner frames" may be 0on veni-ently' manipulated.Figures. 5 and 6,.sh'ow a locking arrangement which may be used inconjunction with" the device, the purpose being to lock one windowagainst the other. F or thispurpose there is provided an eye bolt44-having ashank 45 disposed within an opening-46 formed in'thetopelement of the bottom win-- dow. Adjacent the opening 46 is a member47 having a vertical slot or depression 48 and adeeper horizontal slotor depression 49, the depressed portions of the member 47 being fittedin.

window.

A plate 50 having a hole registering with the opening 46 isprovided'on-theouter surface of the top element. Encircling the shank 45of bolt 44 and confined within the opening 46 is a helical spring '51,one end thereof be dow is a recess '52. A plate 53 is secured to thesaid bottom element adjacent the plate 50 and having a similar holethrough which the free end of the'shank may pass toproect with'intherecess. 52whe'n the bolt is in locked position. When the bolt is inunlocked complementary x grooves f formed in the top element of the.bottom position the eye of the bolt partially recedes within thevertical slot or depression 48 and is thereby fixed in unlocked positionas shown in Figure 6; when the bolt is in locked position the eye of thebolt recedes to a greater extent within the horizontal deeper slot ordepression 49 thereby permitting the extension of the shank within therecess 52 of the top window, as shown in Figure 5.

In constructing a window in accordance with my invention, the innerframe is moved or slid by means of roller elements along the channelsfrom one end of the opening in the outer frame to the other end andfreely swung laterally at any point along the channels. Thisconstruction also permits the inner frame to be completely reversed orturned inside out in a very easy manner and completely confined withinthe outer frame.

It will thus be seen that there is herein described apparatus in whichthe several fea tures of this invention are embodied, and whichapparatus in its action attains the various objects of the invention andis well suited to meet the requirements of practical use.

As many changes could be made in the above construction, and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingshall be interpreted as illustrative and not in a limiting sense.
